Abstract

Filament optique à gradient d'indice à grande largeur de bande comprenant une couche de gainage extérieure possédant un indice de réfraction déterminé, une couche d'arrêt située contre la surface interne de ladite couche de gainage et comprenant un verre de base et au moins un dopant de couche d'arrêt, la quantité du verre de base et du dopant de couche d'arrêt étant sensiblement uniforme sur toute l'épaisseur de la couche d'arrêt, et une âme en verre de haute pureté à gradient d'indice de réfraction disposée à l'intérieur de la couche d'arrêt. Le dopant d'âme comprend un dopant autre que B2 O3 et est introduit sous une proportion propre à établir sur toute la section de l'âme un gradient d'indice de réfraction variant de façon sensiblement continue de ladite interface à l'axe de l'âme, l'indice de réfraction de l'âme à ladite interface étant sensiblement égal ou inférieur à l'indice de réfraction de la couche d'arrêt à l'interface. Application aux télécommunications optiques.
